Standard Method of Test for Evaluation of the Tracking Resistance of Hot-Poured Asphalt Crack Sealant by Dynamic Shear Rheometer (DSR)
|Publication Date:||1 January 2018|
This test method applies to hot-poured asphalt crack sealant used in the construction and maintenance of roadways as specified in M 338 and PP 85.
This test method is used to determine the resistance of hot-poured asphalt crack sealant to tracking and deformation at summer temperatures.
This test method covers the determination of flow and shear thinning propensity in hot-poured asphalt crack sealant with the use of a dynamic shear rheometer and by means of creep-recovery tests.
The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of R 18 are generally considered capable of competent and objective testing/sampling/ins
